db1, you are correct B&H does not list either of the Pentax meters..though Pentax still has both on their website. Calumet still has the digital spot and the Zone version, Adorama only list used? Have not heard anything about them going away..use to have a Spot V, but use a Polaris with a 5 degree now.

At this time we do have the Spotmeter V in stock and we are expecting more
of the digital spotmeters in soon. While it may be possible that Pentax
Corporation in Japan will discontinue them, we have not been advised of that
in the customer service department.

We hope this helps
